Surface tension
Surface tension is an effect
within the surface layer of
a liquid that causes the
layer to behave as an
elastic sheet. It is the
effect that allows insects
(such as the water strider)
to walk on water, and causes

Liquid
A liquid is one of the three
ordinary phases of matter.
It is a fluid whose shape is
usually determined by the
container it fills. Its
volume is fixed under
conditions of constant
temperature and pressure. ... > full story
Boiling point
The boiling point of a
substance is the temperature
at which it can change its
state from a liquid to a gas
throughout the bulk of the
liquid. A liquid may change
to a gas at temperatures
below the boiling point

Viscosity
Viscosity is a measure of
the resistance of a fluid to
deformation under shear
stress. It is commonly
perceived as "thickness", or
resistance to pouring.
Viscosity describes a
fluid's internal resistance

Fluid mechanics
Fluid mechanics is the subdiscipline of continuum mechanics that studies fluids, that is, liquids and gases. It can be further subdivided into fluid statics, the study of fluids at rest, and fluid ... > more -
Fluid dynamics
Fluid dynamics is the subdiscipline of fluid mechanics that studies fluids (liquids and gases) in motion. The discipline has a number of subdisciplines, including aerodynamics (the study of gases) ... > more -
List of phases of matter
This is a list of the different phases of matter including the more exotic ones. Generally phases of matter are distinguished by the pressure and temperature, transforming into other phases as ... > more -
Evaporation
Evaporation is one of the two forms of vaporization. It is the process whereby atoms or molecules in a liquid state (or solid state if the substance sublimes) gain sufficient energy to enter the ... > more -
Superheating
In physics, superheating (sometimes referred to as boiling retardation, boiling delay, or defervescence) is the phenomenon in which a liquid is heated to a temperature higher than its standard ... > more -
Aerodynamics
Aerodynamics (shaping of objects that affect the flow of air, liquid or gas) is a branch of fluid dynamics concerned with the study of forces and gas flows. The solution of an aerodynamic problem ... > more -
Breaking wave
In physics, a breaking wave is a wave whose amplitude reaches a critical level at which some process can suddenly start to occur that causes large amounts of wave energy to be dissipated. At this ... > more -
Drag (physics)
For a solid object moving through a fluid or gas, drag is the sum of all the aerodynamic or hydrodynamic forces in the direction of the external fluid flow. It therefore acts to oppose the motion of ... > more
